In a world just like ours, red glowing strings—called S Lines—suddenly begin to appear above people’s heads. These mysterious lines reveal everyone they’ve had a sexual relationship with. Until now, only one person could see them: a teenage girl named Shin Hyun-Heup.
But when a pair of special glasses starts circulating, allowing anyone to see these connections… society spirals. Secrets unravel. Relationships crumble. And what was once hidden becomes dangerously public.
